Homework Statement
Actually, part of a question on modeling/control systems. I need to find the poles (or, roots) of the cubic function.
Homework Equations
x^3 - 13x + 12 = 0
The Attempt at a Solution
The rule of thumb for the course is that if you get a cubic function then there...

Given are the matrix A (7rows times 3columns):
A = [0,-0.7,-0.1,-0.7,0,0.7,0.1; 0.7,0,-0.7,-0.1,-0.7,0,0.7; 0.1,0.7,0,-0.7,-0.1,-0.7,0]';
And a vector b: b = zeros(7,1); b(7) = 1.7;
Determine with MATLAB what the distance is between b and the column space Col A...
I have another exercise here...

Hello, so I'm currently busy my (first) linear algebra course. We use the book Linear Algebra and it's Application third edition Update (red cover). I noticed that in sections 1.4 and section 1.5 (don't know about the rest yet) that they sometimes describe vectors that are in Rn and sometimes in...
I had to translate the original exercise and left out some details that i thought wasn't relevant. But the equation is correct.
The lsqr was given as solution for the least squares problem in the exercise. The values are different for each student. The the last r value is supposed to be 1.71 +...
The equation is correct, I know it's a little weird
And the A matrix is also correct right? The θ is the first column and the r is the second, or wait why is that wrong? The 'table' is exactly like I wrote in my first post except I made it into columns in MATLAB to calculate the least squares...

The distance traveled by a comet is described with the following equation:
r = B + re cos (θ)
B (Beta) and e are constants
θ 0.88 1.10 1.42 1.77 2.14 2.91 3.85
r 8.27 5.49 3.53 2.50 1.95 1.52 5.21
These were some of the measurements, which can be written in...
